Washington, United States — US magazine The Atlantic on Wednesday published the full exchange of leaked messages between officials laying out plans for an attack on Yemen, as the White House fought fiercely to defend itself over the slip-up.

Details including the times of strikes and types of planes used were shown in screenshots of the chat between President Donald Trump's top officials on the commercial Signal messaging app.

The story broke earlier this week after an Atlantic journalist was accidentally added to the chat, and the magazine said it was revealing full details of the attack plans now because Trump's team insisted that no classified details were involved.

The White House reacted defiantly, launching a coordinated attack in which it slammed the magazine's journalists as "scumbags" and dismissed the story as a "hoax."

"There weren't details, and there was nothing in there that compromised, and it had no impact on the attack, which was very successful," Trump told podcaster Vince Coglianese when asked about the latest revelations.

Vice President JD Vance, who was on the Signal conversation, said The Atlantic had "oversold" the story. 

National Security Advisor Mike Waltz, who has taken responsibility for accidentally adding Atlantic journalist Jeffrey Goldberg to the chat, likewise insisted that the Signal chain revealed "no locations" and "NO WAR PLANS."

Goldberg revealed Monday that Defense Secretary Pete Hegseth sent information in the Signal chat about imminent strikes against the Huthi rebels on 15 March. 

The magazine — which initially said it published only the broad outlines about the attacks to protect US troops — said it had published the full details after the Trump repeatedly denied that any classified details had been included.

The texting was done barely half an hour before the first US warplanes took off -- and two hours before the first target was expected to be bombed.
